Title: unescaping logic is incorrect, and the active_support tests are not actually testing what they claim

Take a look at the commits, hopefully things are self-explanatory. Not sure if you're still maintaining this, but it would be good to pull because the existing parser is largely incorrect when it comes to backslash escapes. Plus, many of the active_support tests _should_ be failing but aren't because of the way the test is written.
